When Harry Potter was brought to 12 Grimmauld Place, Mrs. Weasley assisted him to Ron and Hermione's room upstairs. While they were passing along the dark staircase, Harry saw a row of shrunken heads mounted on plaques on the wall. After a closer look, he noticed that the heads belonged to house-elves. Harry later discovered that beheading old house-elves and mounting their heads on display was something of a tradition in the Black family.[6]
